What is the progression from injury to death?

• A. Inflammation → SIRS → Shock → Multiorgan systemic failure
• B. Injury → Inflammation → Sepsis → Death
• C. Inflammation → Infection → Shock → MODS
• D. Injury → Healing → Regeneration

Answer: (A)

When tissue is injured, the initial response is inflammation to contain damage and begin healing. If this inflammatory response becomes widespread and uncontrolled, it turns into a systemic inflammatory state known as systemic inflammatory response syndrome (SIRS). SIRS disrupts vascular function and tissue perfusion, which can lead to shock. Ongoing poor perfusion and continued inflammatory injury can then cause failure of multiple organ systems, i.e., multiorgan systemic failure, which is a common pathway to death in severe trauma or critical illness. This sequence—inflammation, progression to SIRS, progression to shock, then multiorgan failure—is why the best choice is inflammation → SIRS → Shock → Multiorgan systemic failure. Injury with healing or regeneration describes recovery, not death. Inflammation progressing to infection and sepsis requires an infectious trigger, which is not necessary for the described fatal cascade.
